After John McCain said that Donald Trump was bringing out the "crazies" on the campaign trail, Donald Trump responded this past weekend by questioning the Arizona Republican's status as a war hero.

After Lindsey Graham said Trump should "stop being a jackass" on Tuesday morning, Trump responded by calling the South Carolina Republican "an idiot" during a rambling speech in the senator's home state. Trump didn't stop there, though. He then gave the crowd what he said was Graham's cellphone number and urged them to call it.

.@CBSNews can confirm that the number Trump just read out on stage in South Carolina is Lindsey Graham's cell number.
